The characteristic of certain ferromagnetic materials (magnetic materials containing iron) that causes them to change their physical size when they are subjected to a magnetic field. Magnetostriction is used in some types of transducers (devices that change electrical signals into physical movement).
If a bar of magnetostrictive material is used as the core of a coil through which alternating current is flowing, the changing magnetic field produced by the AC causes the magnetostrictive bar to change its size enough that it will vibrate an object attached to it.
Industry:Aviation
The characteristic of certain materials that causes them to produce a voltage when they are bent or twisted or when pressure is applied to them.
Industry:Aviation
The characteristic of light caused by the different wavelengths of the electromagnetic energy that make up the light. Violet light has the shortest wave lengths, and red, the longest.
Industry:Aviation
The characteristic of light, caused by its wavelength, that gives a color its name. Red, blue, and green are hues.
Industry:Aviation
The characteristics of a material that cause its resistance to increase when light shines on it.
Industry:Aviation
The characteristics of a material that change when the material is exposed to light.
Some materials (photovoltaic materials) produce a voltage when exposed to light, and others (photoconductive materials) change their resistance when exposed to light.
Industry:Aviation
The characteristics of an optical element that contains one or more surfaces that are not spherical.
Industry:Aviation
The charge of compressed air or nitrogen in one side of an accumulator. The air preload is normally about one third of the system hydraulic pressure. When fluid is pumped into the oil side of the accumulator, the air is further compressed, and the air pressure and the fluid pressure become the same.
If the air preload pressure is too low, there will be almost no time between the regulator reaching its kick-in and kick-out pressures, and the system will cycle far more frequently than it should.
If there is no air pressure gage on the accumulator, the amount of air preload may be found by watching the hydraulic system pressure gage as the pressure is slowly bled off the system. The pressure will drop slowly, until a point is reached at which it drops suddenly. This point is the air preload pressure.
Industry:Aviation
The chemical action in which a metallic element is united with oxygen. Electrons are removed from the metal in this process.
Industry:Aviation
The chord of an imaginary airfoil that has the same aerodynamic characteristics as the actual airfoil. The length of the MAC is given for many aircraft, and the CG is expressed in percent of the mean aerodynamic chord (% MAC).
